Flow-induced orientational change of aqueous solution of polymer after an abrupt expansion in planar channel flows
Flow-induced orientational changes of an aqueous polymer solution in planer channels have been studied utilizing optical rheometric technics.Two kinds of 1:4 abrupt expansion channels with the same width and different heights of 1 Day Moisturiser mm and 0.2 mm were tested in the experiments.0.5 wt% xanthan gum solution was examined as the test flui
